You do not need to set up the amount of money you actually want, just the minimum where you would release a game at all. you can then explain what extra features you can add if you get X more, and so on.I know many designers that kickstarted succesfully. The claim actually is they only kickstart if they are gonna release the game ANYWAY.So the number is just set to something dumb low and then the important things are "the goals for X to be achieved."

So you can like ask for 10k or other stupid low number, it doesn't matter.
